Chelsea dropped their first points of the Premier League season as Diego Costa struck twice to rescue a 2-2 draw in a feisty encounter at Swansea City.
Costa, who could have been sent off, capitalised on poor defending to fire the dominant visitors into the lead.
But Gylfi Sigurdsson’s penalty and Leroy Fer’s bundled goal two minutes later turned the game on its head.
Costa scored an acrobatic late second to salvage a point for Antonio Conte’s team, who stay second in the table.
Conte was aiming to become the fourth Chelsea manager to win his first four Premier League games in charge, joining Jose Mourinho, Guus Hiddink and Carlo Ancelotti.
